Simon and Nikolai Haas — twin brothers of actor Lukas Haas, who was a member of Hollywood’s infamous “p—y posse” with Tobey Maguire, Leo DiCaprio and David Blaine — are turning sex into art.

They held their first European exhibition at Zurich’s Galerie Gmurzynska, ahead of Art Basel Switzerland, for a crowd including Diana Picasso, Spyros Niarchos and (oddly) Mischa Barton.

The furniture designers’ show includes a stone table with phallic lamps as legs.

“I really love the fact that something that has taken this much effort, time and money to produce is depicting a lewd sex act,” said Nikolai, who’s made furniture for Lady Gaga, Mario Testino and Donatella Versace.
